Con Bad support for table
It has poor support for table, while table is an important part of article.
Con Bad support for larger documents
Works good for single file documents like READMEs.
Lack support for cross-references, TOCs, document index etc.
Con It doesn't support semantic markup
It's unstructured.
Con Lots of plugins to manage
DokuWiki is highly modular. Even thing like WYSIWYG editors and categories have to be added separately as plugins. This can quickly lead to managing lots of plugins.
